Lung cancer is one of the leading causes cancer-related deaths worldwide with a 5-year survival rate less than 18%. Current treatment modalities include surgery, chemotherapy, radiation therapy, targeted and immunotherapy. Despite advances in therapeutic options, resistance to therapy remains major obstacle effectiveness long-term treatment, eventually insensitivity, poor progression-free survival, disease relapse. Resistance mechanisms stem from genetic mutations and/or epigenetic changes, unregulated drug efflux, tumor hypoxia, alterations microenvironment, several other cellular molecular alterations. A better understanding these crucial for targeting factors involved resistance, establishing novel antitumor targets, developing strategies resensitize cells towards treatment. In this review, we summarize diverse driving radiotherapy, immunotherapy, promising help overcome resistance.

Since the discovery of first microRNAs (miRNAs, miRs), understanding miRNA biology has expanded substantially. miRNAs are involved and described as master regulators major hallmarks cancer, including cell differentiation, proliferation, survival, cycle, invasion, metastasis. Experimental data indicate that cancer phenotypes can be modified by targeting expression, because act tumor suppressors or oncogenes (oncomiRs), they have emerged attractive tools and, more importantly, a new class targets for drug development in therapeutics. With use mimics molecules (i.e., small-molecule inhibitors such anti-miRS), these therapeutics shown promise preclinical settings. Some miRNA-targeted been extended to clinical development, mimic miRNA-34 treating cancer. Here, we discuss insights into role other non-coding RNAs tumorigenesis resistance summarize some recent successful systemic delivery approaches developments anticancer development. Furthermore, provide comprehensive overview trials finally list based on miRNAs.

Cancer chemoresistance is a problematic dilemma that significantly restrains numerous cancer management protocols. It can promote recurrence, spreading of cancer, and finally, mortality. Accordingly, enhancing the responsiveness cells towards chemotherapies could be vital approach to overcoming chemoresistance. Tumour express high level sphingosine kinase-1 (SphK1), which acts as protooncogenic factor responsible for synthesis sphingosine-1 phosphate (S1P). S1P released through Human ATP-binding cassette (ABC) transporter interact with other phosphosphingolipids components in interstitial fluid tumor microenvironment (TME), provoking communication, progression, invasion, metastasis. Also, associated several impacts, including anti-apoptotic behavior, metastasis, mesenchymal transition (EMT), angiogenesis, chemotherapy resistance. Recent reports addressed levels carcinomas, ovarian, prostate, colorectal, breast, HCC. Therefore, targeting S1P/SphK signaling pathway an emerging therapeutic efficiently attenuate In this review, we comprehensively discussed functions, metabolism, transport, signaling. bioinformatic framework, pointed out alterations SphK1 gene expression within different cancers their impact on patient survival, demonstrated protein-protein network SphK1, elaborating its sparse roles. Furthermore, made emphasis machineries resistance tight link S1P. We evaluated all publicly available inhibitors inhibition activity using molecular docking how reduce production might chemoresistance, course treatment prognosis.
